J2EE serves as a reference architecture for enterprise applications. It has gained widespread use over the past few years. For each part of a multi-tier enterprise application, J2EE provides both an implementation technology and a blueprint of how it should be used.

Unfortunately, it is not always easy determine which J2EE technology to use in a given context, or how to use it. This tutorial explores different architectural alternatives available to developers when working with J2EE and describes when it is and is not appropriate to use each one. These guidelines are taken from experiences using J2EE for real-world, mission-critical applications.
